51 + 3x+5 = 107
Simplify the left side:
3x + 56 = 107
Subtract 56 from both sides:
3x = 51
Divide both sides by 3:
x = 51 / 3
x = 17
Angle F and the outside angle of 107, need to equal 180 degrees.
F - 180 - 107 = 73 degrees.
the solution is here,
the coordinate of centre of circle A is (3,2)
and the coordinate of centre of circle B is (3,0).
so the translation point from A to B is (3-0,0-2)=(3,-2).
Now the translation rule is given by (x+h,y+k)
where h is the tranalation anlong the x-axis and k is the translation along the y-axis.
For this problem, translation ruleis (x+3,y-2).
Then, radius of circle A(r1)=2 units
radius of circle B (r2)= 3 units
as the circle A is translated to B, the scale factor is
r2/r1=3/2=1.5
In conclusion, the translation rule for given circles is (x+3,y-2) and its scale factor is 1.5
I think it's 10^-7 hope that helps
Answer:
no because it has three sides
Step-by-step explanation:
Answer:
-x^2 +9x -2
Step-by-step explanation:
f(x) = – x^2 + 6x - 1 and g(x) = 3x
- 1,
(f + g)(x) = f(x) + g(x)
= – x^2 + 6x - 1 + 3x
- 1
Combine like terms
= -x^2 +9x -2
